Why All Mirrors Are Lying to You

The Wow! Signal was a radio signal detected in 1977 that remains the most compelling candidate for an alien radio transmission ever received. 45 years later, and after dozens of failed hours spent trying to catch it again, can we conclude the Wow signal was bogus? Join us today as we discuss a new research paper from the Cool Worlds Lab that explores this question and everything Wow.Written & presented by Prof David Kipping→ Support our research program: https://www.coolworldslab.com/support→ Get Stash here! https://teespring.com/stores/cool-worlds-storeTHANK-YOU to our supporters D.

Does life's early emergence mean life starts easily? Growing evidence shows that life got started very quickly (within ~100 million years) after conditions became suitable for life on Earth (~3.7 billion years ago). This is often taken as evidence that life starts easily, but is this really true? Prof Kipping explains why things aren't as simple as they seem.::More about this Video::► Nutman et al. 2016, "Rapid emergence of life shown by discovery of 3,700-million-year-old microbial structures": http://www.nature.com/nature/journal/v537/n7621/full/nature19355.html► Allwood 2016, "Geology: Evidence of Life in Earth's Oldest Rocks": http://www.nature.com/nature/journal/v537/n7621/full/nature19429.html► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk::Playlists For Channel::Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorldsCool Worlds Research ► http://bit.ly/CoolWorldsResearchGuest Videos ► http://bit.ly/CoolWorldsGuestsQ&A Videos ► http://bit.ly/CoolWorldsQAScience of TV/Film ► http://bit.ly/ScienceMovies::Follow us::SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribeCool Worlds Lab http://coolworlds.astro.columbia.eduTwitter https://twitter.com/david_kippingInstagram https://www.instagram.com/cool.worldsTHANKS FOR WATCHING!!

Thanks to Storyblocks for sponsoring this video! Download unlimited stock media at one set price with Storyblocks: http://storyblocks.com/CoolWorldsToday we explore a problem that has haunted theoretical physicists for decades and remains a topic of active debate - do black holes destroy information? A key precept in quantum theory is that information should be conserved, yet anything that falls into a black hole is seemingly obliterated. How can we reconcile our theories of gravity with that of the quantum world? And could the answer transform the way we look at the Universe...Written & presented by Prof. David Kipping.
